A configuration to reduce a UE PAPR due to a transmission of a PAPR reduction signal into a UE null space. The apparatus establishes a connection with a base station. The apparatus transmits, to the base station, an SFMT report including an indication of a capability of the UE to process a signal form the base station that includes an SFMT transmission. The apparatus receives, from the base station, a downlink PAPR reduction signal based on the SFMT report of the UE.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, wherein the capability is based on the UE utilizing a digital beamforming architecture.
3. The method of claim 1, wherein the SFMT report includes information related to a downlink signal.
4. The method of claim 3, wherein the SFMT report includes information for the downlink signal and the downlink PAPR reduction signal.
5. The method of claim 1, wherein the receiving the downlink PAPR reduction signal comprises receiving the downlink PAPR reduction signal in at least one null space of the UE.
9. The method of claim 8, wherein the UE time advance report is transmitted via radio resource control (RRC) message, medium access control-control element (MAC-CE), or channel state information (CSI) report.
12. The apparatus of claim 11, wherein the SFMT report includes information related to a downlink signal.
16. The method of claim 15, wherein the capability is based on the UE utilizing a digital beamforming architecture.
17. The method of claim 15, wherein the SFMT report includes information related to a downlink signal.
19. The method of claim 18, wherein the SFMT report includes information related to the downlink signal and the downlink PAPR reduction signal.
20. The method of claim 15, wherein the transmitting the downlink PAPR reduction signal comprises transmitting the downlink PAPR reduction signal in at least one null space of the UE.
24. The method of claim 23, wherein the UE time advance report is transmitted via radio resource control (RRC) message, medium access control-control element (MAC-CE), or channel state information (CSI) report.
